[tex]\text{Hello there!}\\\\\text{We're trying to find the surface area of the cube}\\\\\text{We know that the side length of the cube is 13 mm}\\\\\text{To find the surface area, we would use the equation:} \,A = 6a^2\\\\\text{"a" would represent our side length, therefore we plug in 13 to a}\\\\\text{Your equation should look like this:}\\\\A=6(13)^2\\\\\text{Now you would solve}\\\\6(13)^2\\\\\text{Square first}\\\\6(169)\\\\1,014\\\\\large\boxed{\text{Surface area=1,014 millimeters}}[/tex]
[tex]\text{I hope this helps!}\\\text{Best regards,}\\\text{MasterInvestor}[/tex]
